Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a household electric
appliance, more particularly, to a spontaneous electric energy
storage hand tweak torch.
[0002] Hand torch is a commonly used temporary illumination
appliance. Most of the existing hand torches consist of a lamp cap
and a cylindrical casing. The dry batteries within the casing are
connected with the bulb within the lamp cap via a lead. The outer
surface of the casing is provided thereon with a control switch.
This hand torch is widely used because it is simple in structure
and convenient to operate and therefore it has occupied the market
over a long period of time. However, since it is powered by dry
batteries, the replacement rate of batteries is considerably high.
This will not only increase the use-cost but also will cause
considerably difficulty in recycling scrap batteries. A little
carelessness will cause serious environment pollution. Therefore, a
torch powered by an accumulator has been developed. The accumulator
of this torch can be charged by manual operation. Although it
avoids defects of the torch powered by dry batteries, it still has
structural defects. The main expression is found in that the
electric generator needs being driven by a rock arm. It not only
has a complicated structure and a strange profile but also is
inconvenient to operate. Accordingly, the effect of use is not
desirable.
SUMMARY OF THE INVENTION
[0003] In view of the shortages in the prior art, the object of the
present invention is to provide a spontaneous electric energy
storage hand tweak torch, which has a simple structure and is
convenient to operate.
[0004] In order to achieve the aforesaid object, the following
technical solution is adopted in the present invention a
spontaneous electric energy storage hand tweak torch comprises a
lamp cap and a cylindrical casing, wherein the casing comprises a
front casing and a rear casing capable of being bi-directionally
tweaked about an axis, wherein the lamp cap is fixed on the front
casing, wherein the interior of the front casing is provided with
an electric generator, an energy storage element, a circuit board
and a control switch, while the exterior of the front casing is
provided with a push button corresponding to the control switch,
and wherein the output end of the electric generator is connected
with the input end of the circuit board via a lead; the output end
of the circuit board is connected with the energy storage element;
and the rotating shaft of the electric generator is connected with
the rear casing via a gear set.
[0005] The front casing is successively divided into a lamp cap
mounting chamber, an energy storage circuit mounting chamber, an
electric generator mounting chamber and a gear set mounting
chamber, from front to back.
[0006] The front casing and rear casing are encased one another,
wherein the front casino has at the tail portion a thinner cylinder
adapted to the internal diameter of the rear casing with the inner
wall thereof in a stepped shape adapted to the gear set, and the
bottom wall of the rear casing is provided thereon with an annular
protuberance adapted to the internal diameter of the end portion of
said cylinder.
[0007] The energy storage element and circuit board are fixed
within the front casing via a frame, wherein the control switch is
fixed on the circuit board, and the push button is disposed over
the control switch and protrudes outside from the push button hole
in the sidewall of the front casing.
[0008] The circuit board is provided thereon with a rectification
circuit for converting alternating current from the electrical
generator into direct current.
[0009] The circuit board is provided thereon with a voltage
regulator circuit for protecting the light emitting element and the
energy storage element.
[0010] The frame is integrally formed with a condensation shade,
wherein the energy storage element and the frame are provided
therebetween with an elastic pad.
[0011] The electric generator is fixed within the front casing via
a baffle opened with a mounting hole therein.
[0012] The lamp cap comprises a condensation shade, a lens and a
lamp cap cover, wherein the condensation shade is provided in the
front port of the front casing, and the lamp cap is in an annular
shape and screw-connected with the front casing to press the lens
tightly against the opening of the condensation shade.
[0013] The lamp cap cover comprises an inner annular body and an
outer annular body with a V-shaped cross-section, wherein the outer
annular body is longer and screw-connected with the casing, while
the inner annular body is shorter and pressed against the lens
tightly, and a seal ring is provided between the annular contact
surfaces of the lens and the condensation shade.
[0014] The whole body of the hand torch of the present invention is
substantially in the shape of a cylinder. It consists of a front
portion and a rear portion. Said two portions are capable of being
tweaked relative to each other about the axis of the cylinder. The
rear casing is tweaked to drive the gear set connected therewith to
rotate. The gear set still performs the function of amplifying
rotation speed besides driving the electric generator connected
therewith to rotate as a driving member. The rotation of the
electric generator generates alternating current which is
transferred to the circuit board via a lead. A direct current is
output after rectification to charge the energy storage element.
After the energy storage element is fully charged, push the push
button to close the switch to put through the circuit between the
energy storage element and the light emitting element to allow the
light emitting element to shine. Different from the existing rock
arm type energy storage hand torch, the electricity generation
manner of the present invention is to tweak the outer casing of the
torch directly to drive the electric generator to rotate. The
rotation direction is to directly rotate the casing of the torch
bi-directionally about axis thereof without need of rotating a rock
arm within a plane. Therefore, it has simple and compact structure
as well as a regular and uniform profile. Besides, it is convenient
to operate and therefore saves labor. Consequently, it has a very
prominent operation effect.
